< tr bgcolor = "#a2c511" > < th valign = "top" > Mode < th valign = "top" > Command < th valign = "top" > Notes
< tr bgcolor = "#f0f0f0" > < td valign = "top" > Plain Text Editor < td valign = "top" > setTextFormat(PlainText)
< td valign = "top" > Set text with < a href = "#setText" > setText< / a > (); < a href = "#text" > text< / a > () returns plain text. Text
attributes (e.g. colors) can be set, but plain text is always
returned.
< tr bgcolor = "#d0d0d0" > < td valign = "top" > Rich Text Editor < td valign = "top" > setTextFormat(RichText)
< td valign = "top" > Set text with setText(); text() returns rich text. Rich
text editing is fairly limited. You can't set margins or
insert images for example (although you can read and
correctly display files that have margins set and that
include images). This mode is mostly useful for editing small
amounts of rich text. < sup > 1.< / sup >
< tr bgcolor = "#f0f0f0" > < td valign = "top" > Text Viewer < td valign = "top" > setReadOnly(TRUE)
< td valign = "top" > Set text with setText() or < a href = "#append" > append< / a > () (which has no undo
history so is faster and uses less memory); text() returns
plain or rich text depending on the < a href = "#textFormat" > textFormat< / a > (). This mode
can correctly display a large subset of HTML tags.
< tr bgcolor = "#d0d0d0" > < td valign = "top" > Log Viewer < td valign = "top" > setTextFormat(LogText)
< td valign = "top" > Append text using append(). The widget is set to be read
only and rich text support is disabled although a few HTML
tags (for color, bold, italic and underline) may be used.
(See < a href = "#logtextmode" > LogText mode< / a > for details.)
< / table > < / center >
< p > < sup > 1.< / sup > < small > A more complete API that supports setting
margins, images, etc., is planned for a later TQt release.< / small >
< p > TQTextEdit can be used as a syntax highlighting editor when used in
conjunction with < a href = "ntqsyntaxhighlighter.html" > TQSyntaxHighlighter< / a > .
< p > We recommend that you always call < a href = "#setTextFormat" > setTextFormat< / a > () to set the mode
you want to use. If you use < a href = "ntqt.html#TextFormat-enum" > AutoText< / a > then < a href = "#setText" > setText< / a > () and
< a href = "#append" > append< / a > () will try to determine whether the text they are given is
plain text or rich text. If you use < a href = "ntqt.html#TextFormat-enum" > RichText< / a > then setText() and
append() will assume that the text they are given is rich text.
< a href = "#insert" > insert< / a > () simply inserts the text it is given.
< p > TQTextEdit works on paragraphs and characters. A paragraph is a
formatted string which is word-wrapped to fit into the width of
the widget. By default when reading plain text, one newline
signify a paragraph. A document consists of zero or more
paragraphs, indexed from 0. Characters are indexed on a
per-paragraph basis, also indexed from 0. The words in the
paragraph are aligned in accordance with the paragraph's
< a href = "#alignment" > alignment< / a > (). Paragraphs are separated by hard line breaks. Each
character within a paragraph has its own attributes, for example,
font and color.
< p > The text edit documentation uses the following concepts:
< ul >
< li > < em > current format< / em > --
this is the format at the current cursor position, < em > and< / em > it
is the format of the selected text if any.
< li > < em > current paragraph< / em > -- the paragraph which contains the
cursor.
< / ul >
< p > TQTextEdit can display images (using < a href = "tqmimesourcefactory.html" > TQMimeSourceFactory< / a > ), lists and
tables. If the text is too large to view within the text edit's
viewport, scrollbars will appear. The text edit can load both
plain text and HTML files (a subset of HTML 3.2 and 4). The
rendering style and the set of valid tags are defined by a
< a href = "#styleSheet" > styleSheet< / a > (). Custom tags can be created and placed in a custom
style sheet. Change the style sheet with < a href = "#setStyleSheet" > setStyleSheet< / a > (); see
< a href = "tqstylesheet.html" > TQStyleSheet< / a > for details. The images identified by image tags are
displayed if they can be interpreted using the text edit's
< a href = "tqmimesourcefactory.html" > TQMimeSourceFactory< / a > ; see < a href = "#setMimeSourceFactory" > setMimeSourceFactory< / a > ().
< p > If you want a text browser with more navigation use < a href = "tqtextbrowser.html" > TQTextBrowser< / a > .
If you just need to display a small piece of rich text use < a href = "ntqlabel.html" > TQLabel< / a >
or < a href = "ntqsimplerichtext.html" > TQSimpleRichText< / a > .
< p > If you create a new TQTextEdit, and want to allow the user to edit
rich text, call < a href = "#setTextFormat" > setTextFormat< / a > (TQt::RichText) to ensure that the
text is treated as rich text. (Rich text uses HTML tags to set
text formatting attributes. See TQStyleSheet for information on the
HTML tags that are supported.). If you don't call setTextFormat()
explicitly the text edit will guess from the text itself whether
it is rich text or plain text. This means that if the text looks
like HTML or XML it will probably be interpreted as rich text, so
you should call setTextFormat(TQt::PlainText) to preserve such
text.
< p > Note that we do not intend to add a full-featured web browser
widget to TQt (because that would easily double TQt's size and only
a few applications would benefit from it). The rich
text support in TQt is designed to provide a fast, portable and
efficient way to add reasonable online help facilities to
applications, and to provide a basis for rich text editors.
< p > < h3 > Using TQTextEdit as a Display Widget
< / h3 >
< a name = "1-1" > < / a > < p > TQTextEdit can display a large HTML subset, including tables and
images.
< p > The text is set or replaced using < a href = "#setText" > setText< / a > () which deletes any
existing text and replaces it with the text passed in the
setText() call. If you call setText() with legacy HTML (with
< a href = "#setTextFormat" > setTextFormat< / a > (RichText) in force), and then call < a href = "#text" > text< / a > (), the text
that is returned may have different markup, but will render the
same. Text can be inserted with < a href = "#insert" > insert< / a > (), < a href = "#paste" > paste< / a > (), < a href = "#pasteSubType" > pasteSubType< / a > ()
and < a href = "#append" > append< / a > (). Text that is appended does not go into the undo
history; this makes append() faster and consumes less memory. Text
can also be < a href = "#cut" > cut< / a > (). The entire text is deleted with < a href = "#clear" > clear< / a > () and the
selected text is deleted with < a href = "#removeSelectedText" > removeSelectedText< / a > (). Selected
(marked) text can also be deleted with < a href = "#del" > del< / a > () (which will delete
the character to the right of the cursor if no text is selected).
< p > Loading and saving text is achieved using < a href = "#setText" > setText< / a > () and text(),
for example:
< pre >
< a href = "tqfile.html" > TQFile< / a > file( fileName ); // Read the text from a file
if ( file.< a href = "tqfile.html#open" > open< / a > ( < a href = "tqfile.html#open" > IO_ReadOnly< / a > ) ) {
< a href = "tqtextstream.html" > TQTextStream< / a > stream( & file );
textEdit-> setText( stream.< a href = "tqtextstream.html#read" > read< / a > () );
}
< a href = "tqfile.html" > TQFile< / a > file( fileName ); // Write the text to a file
if ( file.< a href = "tqfile.html#open" > open< / a > ( < a href = "tqfile.html#open" > IO_WriteOnly< / a > ) ) {
< a href = "tqtextstream.html" > TQTextStream< / a > stream( & file );
stream < < textEdit-> text();
textEdit-> setModified( FALSE );
}
< / pre >
< p > By default the text edit wraps words at whitespace to fit within
the text edit widget. The < a href = "#setWordWrap" > setWordWrap< / a > () function is used to
specify the kind of word wrap you want, or < a href = "#WordWrap-enum" > NoWrap< / a > if you don't
want any wrapping. Call setWordWrap() to set a fixed pixel width
< a href = "#WordWrap-enum" > FixedPixelWidth< / a > , or character column (e.g. 80 column) < a href = "#WordWrap-enum" > FixedColumnWidth< / a > with the pixels or columns specified with
< a href = "#setWrapColumnOrWidth" > setWrapColumnOrWidth< / a > (). If you use word wrap to the widget's width
< a href = "#WordWrap-enum" > WidgetWidth< / a > , you can specify whether to break on whitespace or
anywhere with < a href = "#setWrapPolicy" > setWrapPolicy< / a > ().
< p > The background color is set differently than other widgets, using
< a href = "#setPaper" > setPaper< / a > (). You specify a brush style which could be a plain color
or a complex pixmap.
< p > Hypertext links are automatically underlined; this can be changed
with < a href = "#setLinkUnderline" > setLinkUnderline< / a > (). The tab stop width is set with
< a href = "#setTabStopWidth" > setTabStopWidth< / a > ().
< p > The < a href = "#zoomIn" > zoomIn< / a > () and < a href = "#zoomOut" > zoomOut< / a > () functions can be used to resize the
text by increasing (decreasing for zoomOut()) the point size used.
Images are not affected by the zoom functions.
< p > The < a href = "#lines" > lines< / a > () function returns the number of lines in the text and
< a href = "#paragraphs" > paragraphs< / a > () returns the number of paragraphs. The number of lines
within a particular paragraph is returned by < a href = "#linesOfParagraph" > linesOfParagraph< / a > ().
The length of the entire text in characters is returned by
< a href = "#length" > length< / a > ().
< p > You can scroll to an anchor in the text, e.g.
< tt > < a name="anchor"> < / tt > with < a href = "#scrollToAnchor" > scrollToAnchor< / a > (). The < a href = "#find" > find< / a > () function
can be used to find and select a given string within the text.
< p > A read-only TQTextEdit provides the same functionality as the
(obsolete) TQTextView. (TQTextView is still supplied for
compatibility with old code.)
< p > < h4 > Read-only key bindings
< / h4 >
< a name = "1-1-1" > < / a > < p > When TQTextEdit is used read-only the key-bindings are limited to
navigation, and text may only be selected with the mouse:
< center > < table cellpadding = "4" cellspacing = "2" border = "0" >
< tr bgcolor = "#a2c511" > < th valign = "top" > Keypresses < th valign = "top" > Action
< tr bgcolor = "#f0f0f0" > < td valign = "top" > UpArrow < td valign = "top" > Move one line up
< tr bgcolor = "#d0d0d0" > < td valign = "top" > DownArrow < td valign = "top" > Move one line down
< tr bgcolor = "#f0f0f0" > < td valign = "top" > LeftArrow < td valign = "top" > Move one character left
< tr bgcolor = "#d0d0d0" > < td valign = "top" > RightArrow < td valign = "top" > Move one character right
< tr bgcolor = "#f0f0f0" > < td valign = "top" > PageUp < td valign = "top" > Move one (viewport) page up
< tr bgcolor = "#d0d0d0" > < td valign = "top" > PageDown < td valign = "top" > Move one (viewport) page down
< tr bgcolor = "#f0f0f0" > < td valign = "top" > Home < td valign = "top" > Move to the beginning of the text
< tr bgcolor = "#d0d0d0" > < td valign = "top" > End < td valign = "top" > Move to the end of the text
< tr bgcolor = "#f0f0f0" > < td valign = "top" > Shift+Wheel
< td valign = "top" > Scroll the page horizontally (the Wheel is the mouse wheel)
< tr bgcolor = "#d0d0d0" > < td valign = "top" > Ctrl+Wheel < td valign = "top" > Zoom the text
< / table > < / center >
< p > The text edit may be able to provide some meta-information. For
example, the < a href = "#documentTitle" > documentTitle< / a > () function will return the text from
within HTML < tt > < title> < / tt > tags.
< p > The text displayed in a text edit has a < em > context< / em > . The context is
a path which the text edit's < a href = "tqmimesourcefactory.html" > TQMimeSourceFactory< / a > uses to resolve
the locations of files and images. It is passed to the
< a href = "#mimeSourceFactory" > mimeSourceFactory< / a > () when quering data. (See TQTextEdit() and
< a href = "#context" > context< / a > ().)
< p > < a name = "logtextmode" > < / a >
< h4 > Using TQTextEdit in LogText Mode
< / h4 >
< a name = "1-1-2" > < / a > < p > Setting the text format to < a href = "ntqt.html#TextFormat-enum" > LogText< / a > puts the widget in a special
mode which is optimized for very large texts. Editing, word wrap,
and rich text support are disabled in this mode (the widget is
explicitly made read-only). This allows the text to be stored in a
different, more memory efficient manner. However, a certain degree
of text formatting is supported through the use of formatting tags.
A tag is delimited by < tt > < < / tt > and < tt > > < / tt > . The characters < tt > < < / tt > , < tt > > < / tt >
and < tt > & < / tt > are escaped by using < tt > & lt;< / tt > , < tt > & gt;< / tt > and < tt > & amp;< / tt > .
A tag pair consists of a left and a right tag (or open/close tags).
Left-tags mark the starting point for formatting, while right-tags
mark the ending point. A right-tag always start with a < tt > /< / tt > before
the tag keyword. For example < tt > < b> < / tt > and < tt > < /b> < / tt > are a tag pair.
Tags can be nested, but they have to be closed in the same order as
they are opened. For example, < tt > < b> < u> < /u> < /b> < / tt > is valid, while < tt > < b> < u> < /b> < /u> < / tt > will output an error message.
< p > By using tags it is possible to change the color, bold, italic and
underline settings for a piece of text. A color can be specified
by using the HTML font tag < tt > < font color=colorname> < / tt > . The color
name can be one of the color names from the X11 color database, or
a RGB hex value (e.g < tt > #00ff00< / tt > ). Example of valid color tags:
< tt > < font color=red> < / tt > , < tt > < font color="light blue"> < / tt > , < tt > < font color="#223344"> < / tt > . Bold, italic and underline settings can be
specified by the tags < tt > < b> < / tt > , < tt > < i> < / tt > and < tt > < u> < / tt > . Note that a
tag does not necessarily have to be closed. A valid example:
< pre >
This is < font color=red> red< /font> while < b> this< /b> is < font color=blue> blue< /font> .
< font color=green> < font color=yellow> Yellow,< /font> and < u> green< /u> .
< / pre >
< p > Stylesheets can also be used in LogText mode. To create and use a
custom tag, you could do the following:
< pre >
TQTextEdit * log = new TQTextEdit( this );
log-> < a href = "#setTextFormat" > setTextFormat< / a > ( TQt::< a href = "ntqt.html#TextFormat-enum" > LogText< / a > );
< a href = "tqstylesheetitem.html" > TQStyleSheetItem< / a > * item = new < a href = "tqstylesheetitem.html" > TQStyleSheetItem< / a > ( log-> < a href = "#styleSheet" > styleSheet< / a > (), "mytag" );
item-> < a href = "tqstylesheetitem.html#setColor" > setColor< / a > ( "red" );
item-> < a href = "tqstylesheetitem.html#setFontWeight" > setFontWeight< / a > ( TQFont::Bold );
item-> < a href = "tqstylesheetitem.html#setFontUnderline" > setFontUnderline< / a > ( TRUE );
log-> < a href = "#append" > append< / a > ( "This is a < mytag> custom tag< /mytag> !" );
< / pre >
Note that only the color, bold, underline and italic attributes of
a < a href = "tqstylesheetitem.html" > TQStyleSheetItem< / a > is used in LogText mode.
< p > Note that you can use < a href = "#setMaxLogLines" > setMaxLogLines< / a > () to limit the number of
lines the widget can hold in LogText mode.
< p > There are a few things that you need to be aware of when the
widget is in this mode:
< ul >
< li > Functions that deal with rich text formatting and cursor
movement will not work or return anything valid.
< li > Lines are equivalent to paragraphs.

< p > The current format's attributes are set with < a href = "#setItalic" > setItalic< / a > (),
< a href = "#setBold" > setBold< / a > (), < a href = "#setUnderline" > setUnderline< / a > (), < a href = "#setFamily" > setFamily< / a > () (font family),
< a href = "#setPointSize" > setPointSize< / a > (), < a href = "#setColor" > setColor< / a > () and < a href = "#setCurrentFont" > setCurrentFont< / a > (). The current
paragraph's alignment is set with < a href = "#setAlignment" > setAlignment< / a > ().
< p > Use < a href = "#setSelection" > setSelection< / a > () to select text. The < a href = "#setSelectionAttributes" > setSelectionAttributes< / a > ()
function is used to indicate how selected text should be
displayed. Use < a href = "#hasSelectedText" > hasSelectedText< / a > () to find out if any text is
selected. The currently selected text's position is available
using < a href = "#getSelection" > getSelection< / a > () and the selected text itself is returned by
< a href = "#selectedText" > selectedText< / a > (). The selection can be copied to the clipboard with
< a href = "#copy" > copy< / a > (), or cut to the clipboard with < a href = "#cut" > cut< / a > (). It can be deleted with
< a href = "#removeSelectedText" > removeSelectedText< / a > (). The entire text can be selected (or
unselected) using < a href = "#selectAll" > selectAll< / a > (). TQTextEdit supports multiple
selections. Most of the selection functions operate on the default
selection, selection 0. If the user presses a non-selecting key,
e.g. a cursor key without also holding down Shift, all selections
are cleared.
< p > Set and get the position of the cursor with < a href = "#setCursorPosition" > setCursorPosition< / a > ()
and < a href = "#getCursorPosition" > getCursorPosition< / a > () respectively. When the cursor is moved,
the signals < a href = "#currentFontChanged" > currentFontChanged< / a > (), < a href = "#currentColorChanged" > currentColorChanged< / a > () and
< a href = "#currentAlignmentChanged" > currentAlignmentChanged< / a > () are emitted to reflect the font, color
and alignment at the new cursor position.
< p > If the text changes, the < a href = "#textChanged" > textChanged< / a > () signal is emitted, and if
the user inserts a new line by pressing Return or Enter,
< a href = "#returnPressed" > returnPressed< / a > () is emitted. The < a href = "#isModified" > isModified< / a > () function will return
TRUE if the text has been modified.
< p > TQTextEdit provides command-based undo and redo. To set the depth
of the command history use < a href = "#setUndoDepth" > setUndoDepth< / a > () which defaults to 100
steps. To undo or redo the last operation call < a href = "#undo" > undo< / a > () or < a href = "#redo" > redo< / a > ().
The signals < a href = "#undoAvailable" > undoAvailable< / a > () and < a href = "#redoAvailable" > redoAvailable< / a > () indicate whether
the undo and redo operations can be executed.
< p > The indent() function is used to reindent a paragraph. It is
useful for code editors, for example in < a href = "designer-manual.html" > TQt Designer< / a > 's code editor < em > Ctrl+I< / em > invokes the indent()
function.

< / h3 >
Constructs a TQTextEdit called < em > name< / em > , with parent < em > parent< / em > . The
text edit will display the text < em > text< / em > using context < em > context< / em > .
< p > The < em > context< / em > is a path which the text edit's < a href = "tqmimesourcefactory.html" > TQMimeSourceFactory< / a >
uses to resolve the locations of files and images. It is passed to
the < a href = "#mimeSourceFactory" > mimeSourceFactory< / a > () when quering data.
< p > For example if the text contains an image tag,
< tt > < img src="image.png"> < / tt > , and the context is "path/to/look/in", the
TQMimeSourceFactory will try to load the image from
"path/to/look/in/image.png". If the tag was
< tt > < img src="/image.png"> < / tt > , the context will not be used (because
TQMimeSourceFactory recognizes that we have used an absolute path)
and will try to load "/image.png". The context is applied in exactly
the same way to < em > hrefs< / em > , for example,
< tt > < a href="target.html"> Target< /a> < / tt > , would resolve to
"path/to/look/in/target.html".

< / h3 >
If there is an anchor at position < em > pos< / em > (in contents
coordinates), the text for attribute < em > attr< / em > is returned,
otherwise < a href = "tqstring.html#TQString-null" > TQString::null< / a > is returned.

< / h3 >
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
< p > If there is an anchor at position < em > pos< / em > (in contents
coordinates), its < tt > href< / tt > is returned, otherwise < a href = "tqstring.html#TQString-null" > TQString::null< / a > is

< h3 class = fn > void < a name = "append" > < / a > TQTextEdit::append ( const < a href = "tqstring.html" > TQString< / a > & text )< tt > [virtual slot]< / tt >
< / h3 >
Appends a new paragraph with < em > text< / em > to the end of the text edit. Note that
the undo/redo history is cleared by this function, and no undo
history is kept for appends which makes them faster than
< a href = "#insert" > insert< / a > ()s. If you want to append text which is added to the
undo/redo history as well, use < a href = "#insertParagraph" > insertParagraph< / a > ().

TQTextEdit is optimized for large amounts text. One of its
optimizations is to format only the visible text, formatting the rest
on demand, e.g. as the user scrolls, so you don't usually need to
call this function.

to be formatted. For example, if after calling < a href = "#setText" > setText< / a > (), you wanted
to know the height of the document (using < a href = "ntqscrollview.html#contentsHeight" > contentsHeight< / a > ()), you
would call this function first.

< p > This property holds the text edit's text.
< p > There is no default text.
< p > On setting, any previous text is deleted.
< p > The text may be interpreted either as plain text or as rich text,
depending on the < a href = "#textFormat" > textFormat< / a > (). The default setting is < a href = "ntqt.html#TextFormat-enum" > AutoText< / a > ,
i.e. the text edit auto-detects the format of the text.
< p > For richtext, calling < a href = "#text" > text< / a > () on an editable TQTextEdit will cause
the text to be regenerated from the textedit. This may mean that
the < a href = "tqstring.html" > TQString< / a > returned may not be exactly the same as the one that
was set.
< p > < p > See also < a href = "#textFormat-prop" > textFormat< / a > .

< p > This property holds the text format: rich text, plain text, log text or auto text.
< p > The text format is one of the following:
< ul >
< li > PlainText - all characters, except newlines, are displayed
verbatim, including spaces. Whenever a newline appears in the text
the text edit inserts a hard line break and begins a new
paragraph.
< li > RichText - rich text rendering. The available styles are
defined in the default stylesheet < a href = "tqstylesheet.html#defaultSheet" > TQStyleSheet::defaultSheet< / a > ().
< li > LogText - optimized mode for very large texts. Supports a very
limited set of formatting tags (color, bold, underline and italic
settings).
< li > AutoText - this is the default. The text edit autodetects which
rendering style is best, < a href = "ntqt.html#TextFormat-enum" > PlainText< / a > or < a href = "ntqt.html#TextFormat-enum" > RichText< / a > . This is done
by using the < a href = "tqstylesheet.html#mightBeRichText" > TQStyleSheet::mightBeRichText< / a > () function.
< / ul >
< p > Set this property's value with < a href = "#setTextFormat" > setTextFormat< / a > () and get this property's value with < a href = "#textFormat" > textFormat< / a > ().
< h3 class = fn > int < a name = "undoDepth-prop" > < / a > undoDepth< / h3 >
< p > This property holds the depth of the undo history.
< p > The maximum number of steps in the undo/redo history. The default
is 100.

< h3 class = fn > < a href = "tqtextedit.html#WordWrap-enum" > WordWrap< / a > < a name = "wordWrap-prop" > < / a > wordWrap< / h3 >
< p > This property holds the word wrap mode.
< p > The default mode is < a href = "#WordWrap-enum" > WidgetWidth< / a > which causes words to be
wrapped at the right edge of the text edit. Wrapping occurs at
whitespace, keeping whole words intact. If you want wrapping to
occur within words use < a href = "#setWrapPolicy" > setWrapPolicy< / a > (). If you set a wrap mode of
< a href = "#WordWrap-enum" > FixedPixelWidth< / a > or < a href = "#WordWrap-enum" > FixedColumnWidth< / a > you should also call
< a href = "#setWrapColumnOrWidth" > setWrapColumnOrWidth< / a > () with the width you want.
< p > < p > See also < a href = "#WordWrap-enum" > WordWrap< / a > , < a href = "#wrapColumnOrWidth-prop" > wrapColumnOrWidth< / a > , and < a href = "#wrapPolicy-prop" > wrapPolicy< / a > .

< h3 class = fn > int < a name = "wrapColumnOrWidth-prop" > < / a > wrapColumnOrWidth< / h3 >
< p > This property holds the position (in pixels or columns depending on the wrap mode) where text will be wrapped.
< p > If the wrap mode is < a href = "#WordWrap-enum" > FixedPixelWidth< / a > , the value is the number of
pixels from the left edge of the text edit at which text should be
wrapped. If the wrap mode is < a href = "#WordWrap-enum" > FixedColumnWidth< / a > , the value is the
column number (in character columns) from the left edge of the
text edit at which text should be wrapped.
< p > < p > See also < a href = "#wordWrap-prop" > wordWrap< / a > .
< p > Set this property's value with < a href = "#setWrapColumnOrWidth" > setWrapColumnOrWidth< / a > () and get this property's value with < a href = "#wrapColumnOrWidth" > wrapColumnOrWidth< / a > ().
